For Hard Sync, BLEP type implementations give the best sounding
results for the fewest cycles that I have found. If you are trying to
do FM with "analog" waveforms and if you want hard sync, wavetable
isn't going to work without adding BLEPs anyway.
If all you want is a band limited sawtooth and you don't need sync,
then wavetable is fine, but simple BLEP related optimizations make
this case relatively cheap.
That being said.... there's some cool things left to do with wavetable
yet.....
